I made a spine animation recorder to save an animation json/atlas files into png files. And I found that an animation will has the same first and last frame. As an example, if the programe play and record the dragon.atlas and dragon.json into png files, I get flying_0000.png to flying_0060.png.
flying_0000.png and flying_0060.png are completely same.
Is that correct? In spine dragon has 0 to 30 frames.
